Title:
METHOD FOR RECOVERING AND REUTILIZING WASTE COTTON TEXTILE
Document Type and Number:
WIPO Patent Application WO/2017/067014
Kind Code:
A1
Abstract:
Provided is a method for recovering and reutilizing a waste cotton textile, comprising the following steps: (1) subjecting the waste cotton textile to immersion treatments in a KH-550 solution, an ammonium chloride solution, and a zinc chloride solution in sequence; (2) subjecting the mixture obtained in step (1) to a pre-oxidation treatment; (3) increasing the temperature of the mixture to 400ºC-900ºC to perform a carbonization treatment with air isolation, and converting same to a porous functional carbon fiber tuft; and (4) collecting the by-product in step (2) and recycling a solvent in a purification system. The carbon fiber tuft prepared by utilizing the method is discontinuous among the fibers and has a large number of holes, and has irregular holes on the surface of the fiber, therefore, the carbon fiber tuft can be used as a carrier for a functional material, such as can be prepared into antibacterial adding materials by adsorbing antibacterial ions such as silver ions, and used for preparing various antibacterial preparations; can also be used as an adsorbing material for a textile dye wastewater, and realizes the highly efficient utilization of waste resources; and can also be widely used in fields such as other water treatments and gas filtration.
